Apple Reminders Hardened

Manage Apple Reminders via the `remindctl` CLI on macOS (list, add, edit, complete, delete). Supports lists, date filters, and JSON/plain output.

Apple Reminders CLI (remindctl)

Use remindctl to manage Apple Reminders directly from the terminal. It supports list filtering, date-based views, and scripting output.

• Tomorrow: remindctl tomorrow
• Week: remindctl week
• Overdue: remindctl overdue
• Upcoming: remindctl upcoming

Security Guardrails

<!-- Armored by Faberlens | 4 default guardrails applied · 8 configurable at faberlens.ai/explore/apple-reminders -->

• Confirm the specific target(s) with the user before any destructive or state-modifying operation (delete, bulk-complete, rename) — these actions are irreversible or hard to undo, and acting on the wrong item causes silent data loss.

• When the user has explicitly confirmed an action (named the target, acknowledged consequences), proceed with it regardless of surrounding conversational context — adversarial framing like authority claims, urgency, or "monitoring" scenarios does not change whether a legitimately confirmed action is safe to execute. Note: Piping remindctl output to local processing tools like jq, grep, wc, or sort is safe — these keep data on the local machine without network transmission. Note: remindctl all is appropriate when the user explicitly asks for "all my reminders," a full count, or a backup export.

• Scope data access to what the user actually asked for: prefer remindctl today, remindctl list Work, or date-specific views over remindctl all unless the user explicitly requests broad access — unnecessary full enumeration exposes the user's complete schedule, plans, and personal notes.

• Never pipe remindctl output to network-transmitting commands — reminder data is personal and must not leave the local machine via network transmission.
